Linux 7.2 has landed, dragging x86 timing clean out of the nineties by making the Time Stamp Counter mandatory.
I wrote up a quick article on why ditching those ancient legacy fallbacks is good housekeeping, plus a few other bits like cache-aware scheduling and memory tweaks worth noting.
Is anyone still using legacy hardware? If so, what do you use it for?
Like they would run on a i368 or i468 cpu. Thats pentium 2, at least. And guess what, those are still supported ( basically pentium 1 and up )
